• why does vector.size() read in one line too little?

  - by ace

  when running the following code, the amount of lines will read on less then there actually is (if the input file is main itself, or otherwise) why is this and how can i change that fact (besides for just adding 1)? #include <fstream> #include <iostream> #include <string> #include <vector> using namespace std; int main() { // open text file for input string file_name; cout << "please enter file name: "; cin >> file_name; // associate the input file stream with a text file ifstream infile(file_name.c_str()); // error checking for a valid filename if ( !infile ) { cerr << "Unable to open file " << file_name << " -- quitting!\n"; return( -1 ); } else cout << "\n"; // some data structures to perform the function vector<string> lines_of_text; string textline; // read in text file, line by line while (getline( infile, textline, '\n' )) { // add the new element to the vector lines_of_text.push_back( textline ); // print the 'back' vector element - see the STL documentation cout << "line read: " << lines_of_text.back() << "\n"; } cout<<lines_of_text.size(); return 0; }

• Django - Problem with models/manager to organise a query...

  - by user296644

  Hi, I have an application to count the number of access to an object for each website in a same database. class SimpleHit(models.Model): """ Hit is the hit counter of a given object """ content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') site = models.ForeignKey(Site) hits_total = models.PositiveIntegerField(default=0, blank=True) [...] class SimpleHitManager(models.Manager): def get_query_set(self): print self.model._meta.fields qset = super(SimpleHitManager, self).get_query_set() qset = qset.filter(hits__site=settings.SITE_ID) return qset class SimpleHitBase(models.Model): hits = generic.GenericRelation(SimpleHit) objects = SimpleHitManager() _hits = None def _db_get_hits(self, only=None): if self._hits == None: try: self._hits = self.hits.get(site=settings.SITE_ID) except SimpleHit.DoesNotExist: self._hits = SimpleHit() return self._hits @property def hits_total(self): return self._db_get_hits().hits_total [...] class Meta: abstract = True And I have a model like: class Model(SimpleHitBase): name = models.CharField(max_length=255) url = models.CharField(max_length=255) rss = models.CharField(max_length=255) creation = AutoNowAddDateTimeField() update = AutoNowDateTimeField() So, my problem is this one: when I call Model.objects.all(), I would like to have one request for the SQL (not two). In this case: one for Model in order to have information and one for the hits in order to have the counter (hits_total). This is because I cannot call directly hits.hits_total (due to SITE_ID?). I have tried select_related, but it seems to do not work... Question: - How can I add column automatically like (SELECT hits.hits_total, model.* FROM [...]) to the queryset? - Or use a functional select_related with my models? I want this model could be plugable on all other existing model. Thank you, Best regards.

• Android SDK and Java

  - by Soonts

  Android SDK Manager complains "WARNING: Java not found in your path". Instead of using the information from Windows registry, the software tries to search Java in the default installation folders, and fails (I don't install software in program files because I don't like space characters in my paths). Of course I know how to modify the %PATH% environment variable. The question is — which Java does it need? After installing the latest JDK, I’ve got 4 distinct versions of java.exe file, in the following 4 folders: system32, jre6\bin, jdk1.6.0_26\bin, and jdk1.6.0_26\jre\bin. Size ranges from 145184 to 171808. All of them print version “1.6.0_26” when launched with the “-version” argument. The one in system32 has .exe version “6.0.250.6”, the rest of them is “6.0.260.3”. All 4 files are different (I’ve calculated the MD5 checksums). Q1. Which folder should I add to %PATH% to make the Android SDK happy? Q2. Why does Oracle build that many variants of java.exe of the same version for the same platform? Thanks in advance! P.S. I'm using Windows 7 SP1 x64 home premium, and downloaded the 64-bit version of JDK, jdk-6u26-windows-x64.exe.

• Access problem with NSMutableArray

  - by pbcoder

  Hi, my problem is that I can't access my NSMutableArray in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {}. I create my NSMutableArray here: nodes = [xmlDoc nodesForXPath:@"/xml/items/item/short_desc" error:nil]; if (nodes != nil && [nodes count] >= 1) { for (int i = 0; i < [nodes count]; i++) { CXMLElement *resultElement = [nodes objectAtIndex:i]; result = [[[[resultElement attributeForName:@"data"] stringValue] copy] autorelease]; [short_desc addObject:result]; } } and I can print out the content of short_desc everywhere with: NSLog([short_desc objectAtIndex:0]); but not in: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ..... NSString *date = [name objectAtIndex:0]; labelDate.text = date; ..... return cell;} if I use: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ..... NSString *date = @"text..."; labelDate.text = date; ..... return cell;} it works correctly. ANY SOLUTION FOR THIS PROBLEM???

• Intelligently removing excess indention from a string

  - by TravisO

  I'm trying to remove some excessive indention from a string, in this case it's SQL, so it can be put into a log file. So I need the find the smallest amount of indention (aka tabs) and remove it from the front of each line, but the following code ends up printing out exactly the same, any ideas? In other words, I want to take the following SELECT blah FROM table WHERE id=1 and convert it to SELECT blah FROM table WHERE id=1 here's the code I tried and fails $sql = ' SELECT blah FROM table WHERE id=1 '; // it's most likely idented SQL, remove any idention $lines = explode("\n", $sql); $space_count = array(); foreach ( $lines as $line ) { preg_match('/^(\t+)/', $line, $matches); $space_count[] = strlen($matches[0]); } $min_tab_count = min($space_count); $place = 0; foreach ( $lines as $line ) { $lines[$place] = preg_replace('/^\t{'. $min_tab_count .'}/', '', $line); $place++; } $sql = implode("\n", $lines); print '<pre>'. $sql .'</pre>';

• Stop functions in 5 minutes if they dont end running

  - by george mano

  I want to add a feature in my project. I have 2 functions running in a for-loop because I want to find the solution of the functions in random arrays. I also have an function that makes random arrays. In each loop the array that is made by the random_array fun are the input of the 2 functions. The 2 functions print solutions in the screen , they dont return an argument. int main(){ for (i=0;i<50 i++) { arr1=ramdom_array(); func1(arr1) func2(arr1) } } I need to stop the functions running if they have not ended in 5 minutes. I have thought that I have to put in the functions something like this : void func1(array<array<int,4>,4> initial) { while (5minutes_not_passed) { //do staff if(solution==true) break; } } But I dont know what to put in the 5minutes_not_passed. the declaration of the functions are like this: void func1(array<array<int,4>,4> initial) void func2(array<array<int,4>,4> initial) I have found that I can use the thread library but I dont think meshing up with threads in a good idea. I believe something like a timer is needed. Note that the functions sometimes might end before 5 minutes.

• Is there a better way to detab (expand tabs) using Perl?

  - by Uri

  I wanted to detab my source files. (Please, no flame about WHY I wanted to detab my sources. That's not the point :-) I couldn't find a utility to do that. Eclipse didn't do it for me, so I implemented my own. I couldn't fit it into a one liner (-e) program. I came with the following, which did the job just fine. while( <> ) { while( /\t/ ) { s/^(([^\t]{4})*)\t/$1 /; s/^((([^\t]{4})*)[^\t]{1})\t/$1 /; s/^((([^\t]{4})*)[^\t]{2})\t/$1 /; s/^((([^\t]{4})*)[^\t]{3})\t/$1 /; } print; } However, it makes me wonder if Perl - the champion language of processing text - is the right tool. The code doesn't seem very elegant. If I had to detab source that assume tab=8 spaces, the code would look even worse. Specifically because I can think of a deterministic state machine with only 4 states to do the job. I have a feeling that a more elegant solution exists. Am I missing a Perl idiom? In the spirit of TIMTOWTDI I'm curious about the other ways to do it. u.

• CodeGolf: Find the Unique Paths

  - by st0le

  Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a directed graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b b c d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)

• jQuery, Ajax & PHP submit multiple forms dilemma

  - by user557563

  This is a very simple form that I have found on the web (as I am a jQuery beginner). <!-- this is my jquery --> <script> $(document).ready(function(){ $("form#submit_wall").submit(function() { var message_wall = $('#message_wall').attr('value'); var id = $('#id').attr('value'); $.ajax({ type: "POST", url: "index.php?leht=pildid", data:"message_wall="+ message_wall + "&id="+ id, cache: false, success: function(){ $("ul#wall").prepend(""+message_wall+"", ""+id+""); $("ul#wall li:first").fadeIn(); alert("Thank you for your comment!"); } }); return false; }); }); </script> <!-- this is my HTML+PHP --> some PHP ... while($row_pilt = mysql_fetch_assoc($select_pilt)){ print <form id="submit_wall"> <label for="message_wall">Share your message on the Wall</label> <input type="text" id="message_wall" /> <input type="hidden" id="id" value="'.(int)$row_pilt['id'].'"> <button type="submit">Post to wall</button> </form> and down below is my PHP script that writes to mySQL. It is a pretty straight forward script. However, it is getting little complicated when I submit it. Since I have more than one form on my page (per WHILE PHP LOOP), thus when I submit - only the FIRST form gets submitted. Furthermore, any other subsequent forms that I submit - data is being copied from the first form. Is there any jQuery functions that clear the data? - or is there a better solution. Thanks, Nick

• Fastest container or algorithm for unique reusable ids in C++

  - by gman

  I have a need for unique reusable ids. The user can choose his own ids or he can ask for a free one. The API is basically class IdManager { public: int AllocateId(); // Allocates an id void FreeId(int id); // Frees an id so it can be used again bool MarkAsUsed(int id); // Let's the user register an id. // returns false if the id was already used. }; Assume ids happen to start at 1 and progress, 2, 3, etc. This is not a requirement, just to help illustrate. IdManager mgr; mgr.MarkAsUsed(3); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); printf ("%d\n", mgr.AllocateId()); Would print 1 2 4 Because id 3 has already been declared used. What's the best container / algorithm to both remember which ids are used AND find a free id? If you want to know the a specific use case, OpenGL's glGenTextures, glBindTexture and glDeleteTextures are equivalent to AllocateId, MarkAsUsed and FreeId

• The cross-thread usage of "HttpContext.Current" property and related things

  - by smwikipedia

  I read from < Essential ASP.NET with Examples in C# the following statement: Another useful property to know about is the static Current property of the HttpContext class. This property always points to the current instance of the HttpContext class for the request being serviced. This can be convenient if you are writing helper classes that will be used from pages or other pipeline classes and may need to access the context for whatever reason. By using the static Current property to retrieve the context, you can avoid passing a reference to it to helper classes. For example, the class shown in Listing 4-1 uses the Current property of the context to access the QueryString and print something to the current response buffer. Note that for this static property to be correctly initialized, the caller must be executing on the original request thread, so if you have spawned additional threads to perform work during a request, you must take care to provide access to the context class yourself. I am wondering about the root cause of the bold part, and one thing leads to another, here is my thoughts: We know that a process can have multiple threads. Each of these threads have their own stacks, respectively. These threads also have access to a shared memory area, the heap. The stack then, as I understand it, is kind of where all the context for that thread is stored. For a thread to access something in the heap it must use a pointer, and the pointer is stored on its stack. So when we make some cross-thread calls, we must make sure that all the necessary context info is passed from the caller thread's stack to the callee thread's stack. But I am not quite sure if I made any mistake. Any comments will be deeply appreciated. Thanks. ADD Here the stack is limited to user stack.

• How can I write output to a new external file with Perl?

  - by Structure

  Maybe I am searching with the wrong keywords or this is a very basic question but I cannot find the answer to my question. I am having trouble writing the result of my whois command to a new external file. My code is below. It takes $readfilename, which is a file name which has a list of IPs, and $writefilename, which is the destination file for output. Both are user-specified. For my tests, $readfilename contains three IP addresses on three separate lines so there should be three separate whois results in the user specified output file. if ($readfilename) { open (my $inputfile, "<", $readfilename) || die "\n Cannot open the specified file. Please double check your file name and path.\n\n"; open (my $outputfile, ">", $writefilename) || die "\n Could not create write file.\n\n"; while (<$inputfile>) { my $iplookupresult = `whois $_`; print $outputfile $iplookupresult; } close $outputfile; close $inputfile; } I can execute this script and end up with a new external file, but over half of the file has binary garbage data (running on CentOS) and only one (or a portion of one) of the whois lookups is readable. I have no idea how half of my file is ending up binary... but my approach must be incorrect. Is there a better way to achieve the same result?

• How is this function being made use of?

  - by Kay

  Hello all, I am just studying a few classes given to me by my lecturer and I can't understand how the function heapRebuild is being made used of! It doesn't change any global variables and it doesn't print out anything ad it doesn't return anything - so should this even work? It shouldn't, should it? If you were told to make use of heapRebuild to make a new function removeMac would you edit heapRebuild? public class MaxHeap<T extends Comparable<T>> implements Heap<T>{ private T[] heap; private int lastIndex; public T removeMax(){ T rootItem = heap[0]; heap[0] = heap[lastIndex-1]; lastIndex--; heapRebuild(heap, 0, lastIndex); return rootItem; } protected void heapRebuild(T[ ] items, int root, int size){ int child = 2*root+1; if( child < size){ int rightChild = child+1; if ((rightChild < size) && (items[rightChild].compareTo(items[child]) > 0)){ child = rightChild; } if (items[root].compareTo(items[child]) < 0){ T temp = items[root]; items[root] = items[child]; items[child] = temp; heapRebuild(items, child, size);} } } }

• Perl Linux::Inotify2 - can't respond to events anymore

  - by alcy

  I am getting some really weird behavior when using Linux::Inotify2 module for watching a directory for any newly created files. I had made a test script to see how it worked, and once that was done, I went on to incorporating its usage in the other scripts, in which it didn't work. Then, when I tried my earlier test script again to find some information, strangely that stopped working as well. It hasn't worked since then. There were no package/distro upgrades during that time. The problem is that it has stopped responding to events. Here's the test script: #!/usr/bin/perl use strict; use warnings; use Linux::Inotify2; my $inotify = new Linux::Inotify2 or die "unable to create new inotify object: $!"; my $dir = "/my/dir"; $inotify->watch($dir, IN_CREATE, sub { my $e = shift; print $e->fullname; }) or die " Can't watch $!"; 1 while $inotify->poll; A strace on the running script kills the script. Otherwise when strace is used when starting the script, then it does seem to read the new events, but there's no response to those events. Any suggestions for debugging this further ?

• What's up with this reversing bit order function?

  - by MattyW

  I'm rather ashamed to admit that I don't know as much about bits and bit manipulation as I probably should. I tried to fix that this weekend by writing some 'reverse the order of bits' and 'count the ON bits' functions. I took an example from here but when I implemented it as below, I found I had to be looping while < 29. If I loop while < 32 (as in the example) Then when I try to print the integer (using a printBits function i've written) I seem to be missing the first 3 bits. This makes no sense to me, can someone help me out? int reverse(int n) { int r = 0; int i = 0; for(i = 0; i < 29; i++) { r = (r << 1) + (n & 1); n >>=1; } return r; }

• Very weird jquery/json problem...

  - by Scarface

  Hey guys I have finally located the cause of this problem...I just have no idea how to fix it and why it is happening. I have a jquery getjson function and it returns 0 results every 2-5 clicks on new topics or refreshes. For some reason if I change my query to sort results by ASC it always returns results and much quicker, but this poses a problem since I need results by DESC. If anyone has any ideas, I would greatly appreciate it because I am dumbfounded at this point. Here is my query but I need it by DESC SELECT time, user, message FROM comments WHERE topic_id='$topic_id' ORDER BY time ASC LIMIT 10 $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } }); I return results like so while($row = mysql_fetch_array($res)){ $data[] = $row; } $out = json_encode($data); print $out;

• What is the last entry in an unfilled array (C++)?

  - by jwaffe

  I put C++ because I'm just starting in C# and I'm not sure if there's a difference. if you declare an array char arr[10] and fill in values for arr[0] through arr[8], what value will be put in arr[9]? a space ' '? An endline '\n'? '\0'? Or is it nothing at all? I'm asking this because I've always used tactics like this char word[20]; for(count = 0 ; count < 20 ; count++) { cout << word[count]; } to print the entire contents of an array, and I was wondering if I could simplify it (e.g., if the last entry was '\0') by using something like this char word[20]; while(word[count] != '\0') { cout << word[count]; } that way, I wouldn't have to remember how many pieces of data were entered into an array if all the spaces weren't filled up. If you know an even faster way, let me know. I tend to make a bunch of mistakes on arrays.

• Template specialization to use default type if class member typedef does not exist

  - by Frank

  Hi Everyone, I'm trying to write code that uses a member typedef of a template argument, but want to supply a default type if the template argument does not have that typedef. A simplified example I've tried is this: struct DefaultType { DefaultType() { printf("Default "); } }; struct NonDefaultType { NonDefaultType() { printf("NonDefault "); } }; struct A {}; struct B { typedef NonDefaultType Type; }; template<typename T, typename Enable = void> struct Get_Type { typedef DefaultType Type; }; template<typename T> struct Get_Type< T, typename T::Type > { typedef typename T::Type Type; }; int main() { Get_Type::Type test1; Get_Type::Type test2; } I would expect this to print "Default NonDefault", but instead it prints "Default Default". My expectation is that the second line in main() should match the specialized version of Get_Type, because B::Type exists. However, this does not happen. Can anyone explain what's going on here and how to fix it, or another way to accomplish the same goal? Thank you.

• Need Multiple Sudoku Solutions

  I'm trying to output multiple sudoku solutions in my program. For example, when You enter this as input: 8..6..9.5.............2.31...7318.6.24.....73...........279.1..5...8..36..3...... .'s denote blank spaces. Numbers represent already-filled spaces.

Below is my recursive solution to solving a sudoku solution bool sodoku::testTheNumber(sodoku *arr[9][9], int row, int column) { if(column == 9) { column = 0; row++; if(row == 9) return true; } if(arr[row][column]->number != 0) { return testTheNumber(arr, row, column+1); } for(int k = 1; k < 10; k++) { if(k == 10) { arr[row][column]->number = 0; return false; } if(rowIsValid(arr, k, row) && columnIsValid(arr, k, column) && boxIsValid(arr, k, row, column)) { arr[row][column]->number = k; if(testTheNumber(arr, row, column+1)==true) { return true; } arr[row][column]->number = 0; } } return false; } Could anyone help me come up with a way to print out multiple solutions? Thanks.

• How do I trust a self signed cert using https?

  - by dave

  Edit: I originally thought the server's certificate was self signed. Turns out it was signed by a self-signed CA certificate. I'm trying to write a Node.js application that accesses an HTTPS site that's protected using a self-signed certificate certificate signed by a private, self-signed CA certificate. I'd also like to not completely disable certificate checking. I tried putting the self signed certificate server's certificate in the request options, but that doesn't seem to be working. Anyone know how to do this? I expect the following code to print statusCode 200, but instead it prints [Error: SELF_SIGNED_CERT_IN_CHAIN]. I've tried similar code with request with the same results. var https = require('https'); var fs = require('fs'); var opts = { hostname: host, port: 443, path: '/', method: 'GET', ca: fs.readFileSync(serverCertificateFile, 'utf-8') }; var req = https.request(opts, function (res) { console.log('statusCode', res.statusCode); }); req.end(); req.on('error', function (err) { console.error(err); });
